  Log Message:
  -----------
  [LoopPeel] Handle constants when updating exit values when peeling last.

Account for constant values when updating exit values after peeling an
iteration from the end. This can happen if the inner loop gets unrolled
and simplified.

Fixes https://github.com/llvm/llvm-project/issues/140442.
